Abstract

The Olympic iron oxide Cu-Au (IOCG) Province occurs along the eastern margin of the Gawler craton nucleus where oxidized (magnetite-series), A-type granitoid plutons of the 1595-1575 Ma Hiltaba Suite were emplaced into an accreted Paleoproterozoic terrane, and where mafic volcanic rocks of the lower Gawler Range Volcanics are most abundant. This magmatism comprises the central part of a diachronous corridor of bimodal I-, A- and subordinate S-type intrusions that extends across the Gawler and Curnamona cratons, and was emplaced in a distal continental retro-arc setting during amalgamation of the North and South Australia cratons. IOCG mineralisation mostly formed during a short lived episode of NNW-SSE extension that approximately coincided with eruption of the Gawler Range Volcanics (ca. 1595-1590 Ma), but was preceded and followed by more protracted NW-SE to NNW-SSE contraction. The deposits were emplaced along ENE- to NE-trending extensional faults near their intersections with major NNW- to NW-trending faults in the hangingwall of first-order terrane boundary faults, such as the Elizabeth Creek and Pine Point Fault Zones. Area selection guidelines for further discoveries beneath the extensive cover are considered at subprovince, district and deposit scales.
